l' vis to providea locksocon'structed that it mayy iV be actuated to releasethe door up'onmwhich it is mounted with less exertion and greater One of the objects of the present/invention facility than locks as ordinarily constructed and particularly such as are employed on the doors; of automobiles, the invention likewise contemplating,iinthis, 'connectiomf a lock Which maybe manipulated Without the necesl "1li sity of resorting to repeated attempts'at op 'y v eratingthe vsame to retract the bolt as visfreq uently'necessary in the usel of some typesof `AV.l'yclgs for this purpose ordinarily employed. :Anotherobject of the invention is toso construct the lockthat a singlepull upon an?V i f Yactuating hand lever which constitute'sa part iofthe lock, Will serve not only to retract the .Y bolt butnlso to permit of the pull being transl [fthe doors of closed automobiles, which lock*V mitted to the door in orderV to swing the `'door Y to. open position, sothat. thedoo'r may be Vopened' as readily as `though the lock-were not 'present VAnotherobjelct of the-inventionislto pro'. vide a lock designed .particularlyfor use upon I l :j may be actuated fromthe inner side ofthe door by mere pressureexerted.againstanactustingV element, .sothat voutward pressure is i yexerted-upon thedoortoswing the sameto i Another object 'Qpen p'osition-atthe samemoment-the lock :boltis'retracted through the aCtuaQIl Of Said rellement; A
